T0 ativwm t may concern:

Be it known that I, CARY `W. CRAWFORD,

a citizen of the United States, residing at the city of Los Angeles, inthecounty of i Angeles and State of California, have invented new anduseful Improvements in Vehicle-Springs, of which the following is aspecification.'

.111." Projecting from the lower v11 is apin l2 on which is rockablymounted My invention relates primarily to springs for vehicles travelingon streets or roads and the object thereof is to provide; a vehiclespring of great mobility.

A further object is to provide a spring that possesses the minimumamountf rebound action whereby the danger of brealiing the spring'isreduced to the minimum.

My improved spring consists of the combination of leaf and coil springs.if;

In the drawings forming a part of'this application: Figure 1 is a Sideelevation of one of my improved springs showing it applied to the rearportion of an automobile. Fi g. 2 is a plan of the parts shown inFig- 1. v Fig. 3 is a side elevation of my improved spring showing itapplied to the front portion of l automobile. Fig. 4 is an enlargedvertical section of the casing and coil springs:v` Fig. 5 is amodification ofthe mnunting of the leaf spring.

In the secured bearing plate end ofplate supporting plate 13. Leafspring 14 is v mounted intermediate its ends on plate 15:3..v

One end of spring 14 is mounted on the rear axle 15. The other end ofspring 14 pron jects into the spring casing 1G in which the coil springsare carried. Within casing 16 is a split follower 17in the center ofwhich the end of spring 14 is received. The end ofr spring 14 within thefollower may be globular as shown in Fig. 4, or cylindrical as shown inFig. 5. To allow the follower to have a transverse motion as to thecasing a AU-shaped guide 18 straddles the follower.

A spring 19 assists in holding the follower central in the guide. Withinthe casing and at one side of the guide is a coil thrust spring 20. Onthe other side of the guide is the rebound spring; Where' greatermobility is desired the rebound spring is composed of a light centralspring 21 which sets in a cup 2.2. This cup is supported by the heavyrebound spring Q3 which disk 24 which is placed within the casing at theand thereof to hold the casing from collapsing when. nut 25 .is screwedupon the cas ingr In springs at vthe rea-r of the vehicle the fthrustsprings are inthe bottom of the casing and the rebound springs'are inthe top.' In springs at the front of the vehicle the lthrust springs arein the top vand the rebound springs are in the bottom of the casing.: lfdesired a single reboundspring may be used in each casing. At the rear Iprefer to attach the casing rigidly to the frame'. At the front I preferto attach the casing to .the'frame by a pivot 26 as shown in 3 oso thatit--maycscillate to accommodate itself to the movementof the end of theleaf spring last spring hears upon .,fhczythe vehiclepasses over anobstruction.

When the casing is frame follower 17 could justfit the casing andguide1S could be omitted. A slot 27'is provided in the casing to allow forlongitudinal movement ofthe end of the leaf spring as tothe casing andfor assembling. At the center to the front axle 28.

From the foregoing it will be seen thatone end of the leaf spring issupported by 'a coil thrust spring and onthe other side of thisexcessive rebound is prevented by suitcoi'lsprings, thus providing avery etlicient mobile'spring'in which the danger of breakage by reboundis reduced to the. minimum.

Having described my invention what I claim is: y i

VA Ivehicle springcomposed of a leaf spring adapted to be connectedat or near the center .and at one end. to different parts of theVehicle; and a spring vconnection on the other end of the leaf springadapted Ato be secured to a part of the vehicle, said last springconnectioncomprising a casing pivotally connected to the frame of thesaid casing having a slit in one side thereof; a follower within saidcasing in which the end of the leaf spring is received; a reboundspringen one side of said follower;

thrust yspring on the other side of said follower. v

2. A vehicle spring composed-'of a leaf spring adapted the center and atone end of the-vehicle; and a spring connection on" the other end of theleaf sprugedapted to pivotallyponnected to the vehicle, Y
